Abstract: A time from covering to edit or broadcast is shortened and also management and handling of materials are made simpler. Encoder 1A compresses digital video signal DVS obtained by camera into encoded data DVA of low resolution. Encoder 1B compresses the digital video signal DVS into encoded data DVB of high resolution. The encoded data DVA of low resolution and encoded data DVB of high resolution are stored in storage medium 4. Moreover, the encoded data DVA of low resolution is transmitted to broadcasting station by transmitter 7 simultaneously with storing in the storage medium 4. In the broadcasting station, edit is performed based on the encoded data DVA of low resolution and edit decision list is transmitted to video recording apparatus. The edit decision list is stored in the storage medium 4. When the storage medium 4 is brought into the broadcasting station, the encoded data DVB of high resolution is broadcast in accordance with edit decision list.

Abstract: When separating a composite video signal into a luminance signal component and the chrominance signal component by the use of filtering, a high frequency cross-talk component of the luminance signal is present in the chrominance signal and this may be cancelled using a horizontal correlator that imparts time delays and detects maximum and minimum levels relative to a reference level. In such luminance cross-talk cancellation by means of the horizontal correlator the usable chrominance signal length is shortened by almost one wave length out of four, thereby reducing the usable chrominance signal each time such luminance/chrominance signal separation occurs in a dubbing operation, for example. By utilizing two chroma separators in series each including a nonadditive mixer circuit, the resultant output from the second chroma separator circuit has substantially the same length as the portion of the composite video signal fed as the input.
